NGC 4150 is a lenticular galaxy of the Hubble type S0 in the constellation Haar der Berenike in the northern sky . The radial speed of 208 km / s is too slow to be a reliable indicator of distance. In fact, the resulting distance estimate of 10 million light years is far smaller than the redshift-independent distance estimate of 30 to 65 million light years. At a distance of about 50 million light years, the galaxy is about 30,000 light years in diameter.
In the same area of the sky is u. a. the galaxy NGC 4136 .
The object was discovered by William Herschel on March 13, 1785 .
